(3) The LF411A is 100% tested to this specification. The LF411 is sample tested to insure at least 90% of the units meet this specification.
(4) The input bias currents are junction leakage currents which approximately double for every 10°C increase in the junction temperature,
T
j
. Due to limited production test time, the input bias currents measured are correlated to junction temperature. In normal operation the
junction temperature rises above the ambient temperature as a result of internal power dissipation, P

is the
thermal resistance from junction to ambient. Use of a heat sink is recommended if input bias current is to be kept to a minimum.
(5) Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously in accordance with
common practice, from ±15V to ±5V for the LF411 and from ±20V to ±5V for the LF411A.
